It is suitable for studying low-frequency microinstabilities and the … WebGyrokinetic (GK) theory aims to describe plasma particle motion in terms of drifts of particle gyrocentres, rather than the usual combination of gyromotion and drifts of the …
WebApr 9, 2015 · This approach has the potential to mitigate the cancellation problem considerably. In this paper, we implement pullback mitigation to globally simulate shaped plasmas of an elongated tokamak and the Wendelstein 7-X stellarator (W7-X). The fully gyrokinetic system of equations is solved in these simulations for all particle species. WebJan 28, 2024 · Aiming to solve the problems of poor dynamic response characteristics and the weak anti-jamming capability of the conventional proportional–integral–derivative (PID) controlled pump-motor servo system (PMSS) under the actual working environment, this study created a brand new hybrid …
WebThe particle gyro-center motion is calculated by Lagrangian equations in the flux coordinates, which allows for accurate particle orbit integration thanks to the separation between fast parallel motion and slow perpendicular drifts. WebSep 1, 1987 · To circumvent the numerical difficulties involving coordinate transformations, the simulation scheme described in Ref. [l] used the analytically transformed gyrokinetic Vlasov equation in the particle variable space by assuming that, non- linearly, ion perpendicular temperature is zero.
